waiting for the 6 speed over the 4 on the 08's?
4speed vs. 6speed
I don`t know for sure. Time will tell I believe these are the new trannys being built at GM Powertrain in Toledo, Ohio
I have a 6-speed in my Silverado and love it! Different class I know with it being a 2500hd.
Six is greater than four.
Definite on the 6 speed, less RPM's, less wear and tear, better mileage, better crusing sppeds on the Highway, oh I'll the 6 please........:great:
